the water from the flush tank and to so construct the valve as tofacilitate its installation in a practical and satisfactory manner inconventional 'fiush tanks.

In carrying the invention into effect, I have evolved and producedwhat Ibelieve to be an unusually practical arrangement of details expresslymade for intimate cooperation with each other in a manner to provide anefficient valve arrangement which will fulfill the requirements of astructure of this class in a more satisfactory manner than those nowknown to me.

The specific details and their association will become more readilyapparent from the following description and drawings.

In the drawings:

Figure 1 is an elevational view of the mechanism within aconventionalflush tank, the arrangement being in accordance with the presentinvention. 3

Figure 2 is an enlarged detail view in section and elevation showing theprincipal elements of the improved control valve construction.

Figure 3 is a guide sleeve supporting bracket.

Itserves to operate a crank arm 12 on the interiorhaving a lifting pin 13. '14: represents the discharge pipe which leadsto the hopper (not'shown).

Attention is now invited to the control valve mechanism, detailed inFigure 2. To begin with the valve seat fitting is designated generallyby the reference character 15. It comprises a screw threaded nipple 16having'a fiangej17, provided with a valve seat 18. A

nipple. A coupling neck is indicated at20,

and this serves to accommodate the substantially L-shaped orrightangular bracket 21. The stem 22 ofthe bracket is threaded intotheneck and held therein by a retainwhichv the lower end of the guidesleeve 26 is fitted and held as, here shown. There is a top bracket 27,designed to; accommodate The reference character 19 designates theretaining nut carried by the a rocker arm 28, having an adjustablecounter-balance weight 29 and complemental stops 30 and 31 respectively.Connected to the intermediateportion of this rocker T arm and dependingtherefrom into the guide sleeve is a lifting -'wire 32, having a ring 33on its lower end which cooperates with an inwardly pressed annular bead34, on the intermediate portionof thevalve tube 35.

The valve tube has a similar externalbead at 36, and has its lower endfashioned as at 37 to form a connector for the ring nut 38.

The ring'nut holds the valve annulus 39 in .place and in a position toengage the valve seat 18. V

In practice, itis obvious that when the handle 11 is rocked in the usualwayit actu ates .the crank arm 12 and through the medium of the pin 13cooperates with the rocker arm 28, the latter being moved on its pivot,obviously through the medium of the wire 32 and the complemental ring 33and bead 34, the tube 35 is elevated. This raises the valve 39 off ofthe seat and allows the water to discharge in an obvious manner.Theaction of theparts is smooth, dependable and without hitch.

A careful consideration of the description in conjunction with thedrawings willenable the reader to obtain a clear understanding of theconstruction, the assembly, the method of operation, and the featuresand advantages. Thereforea more lengthy description is believed to beunnecessary.

Minor changes in the shape, size and rearrangement of details comingwithin the field of invention claimed may be' resorted to, in actualpractice, if desired.

I claim: c g

ZIn a'structur'e of the class described, in combination a dischargevalve construction comprising a' fitting including a supporting flange,a depending'nipple, a bevelled valve seat,- and-an'attachi-ng neck, anL-shaped bracket detachably' connected with said neck, and provided witha clamp disposed centrally above said nipple, a sleeve having its lowerend-fitted in said clamp, and rising vertically therefrom above saidnipple, a rocker armpivotallymounted from the upper end portion of saidsleeve,- a tube slidable withinsaid sleeve, said tube being providedwith an internal shoulder forming bead, a ring engageable with saidbead, a Wire connecting said ring with the intermediate portion of saidrocker arm, and a detachable valve element on the lower end of saidtubecooperable with saidvalve seat.

3. In a'- structure of the class described, a fitting for use inassociation with the valve balance weight carried by said arm,complemental stops on said rocker arm and bracket, said rocker arm beingprovided intermediate its ends with a pendant valve sleeve lifting wiredepending into the sleeve and provided at its bottom with a ring tocooperate with the inward annulus of the valve sleeve.

5. In a control valve of the class described, an open ended tubeprovided adjacent its upper end with an inwardly pressed beadconstituting a lifting shoulder having its lower end screw threaded andprovided above said lower end with an outstanding collar forming bead, aring nut carried by the screw threaded end portion, a valve annulusbetween the nut and collar, said valve annulus being provided with abevelled seating surface.
